Help - Leaking oil (timing cover)

[wackotecho]

Well I am going to try even possible sealant to try to stop the leak rather than try to replace the seal at this point as it looks like a horrible job while in the car.

Well today, i spent some time with Maxx Grey RTV Sealant and my 318ti, well the M44 anyway, so here is the good news, it appears to no longer leak (quick test performed about 3 hour after application of sealant), will check it around lunch time as that will be fully cured by then.

Where did you apply it?

[wackotecho]

I applied it to the outside after a degrease and scrub of the area. My next door neighbour uses it to seal any leaks on his drag engine.

My leak was just under the timing chain tensioned bolt area it was the seal you posted the pic of, what a pain in the rear end.

If this stops the leak long enough for my original engine to be fully rebuilt with all new seals I will be happy.

Let us know if that was the seal leaking...I am hoping mine is ok!

You are fortunate to have a 2nd engine.

I can tell you it was definitely that seal, looks like someone tried to replace all the timing gaskets and seals and damaged that one in the process.

If you do plan on changing yours I would recommend you lower your sump and loosen the head to allow clearance to get that seal in.

I will post a pic of my old engine which was most helpful with this issue.

Give me about 10 minutes to take the photo of the seals and engine.

I hope this is helpful for you.

I have the same leak issue with my 98 318Ti and I'm wondering if the silicone sealant is holding and solved your oil leak. Thanks.

The leak is under control, I did notice that the crack case breather was not functioning and this was also part of the problem, basically positive pressure had no place to go and forced oil out of seal.

Have sorted this crank case pressure problem out and found the leak is now completely gone.
